Introduction: The asphalt pressure aging system is designed and manufactured in accordance with the requirements specified in the industry standard JTG E20-2011 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering" T0630-2011 "Accelerated Asphalt Aging Test for Pressure Aging Containers", the petrochemical industry standard SH/T 0774-2005 "Accelerated Asphalt Aging Test Method (PAV Method)", and reference to the test methods of ASTM D6521 and AASHTO PPI in the People's Republic of China. The asphalt pressure aging system can simulate the oxidative aging of asphalt during road use, and is suitable for evaluating the antioxidant aging ability of different asphalt under test temperature and pressure conditions. Features: 1. This system consists of a PAV-1-1 asphalt pressure aging chamber and a PAV-1-2 asphalt aging vacuum chamber. 2. The manufacturing, installation, and use of this system comply with the relevant provisions of the Special Equipment Safety Supervision Regulations. 3. This system is equipped with a computer, and the high-voltage aging test is controlled and monitored by the computer. The entire test process is automatically completed by computer control. 4. All technical indicators of this system meet the requirements of similar imported equipment, making it an ideal substitute for imported equipment. Technical parameters: 1. PAV-1-1 Asphalt Pressure Aging Box Power supply voltage: AC (220 ± 10%) V, 50Hz; Power 1.1kW Working volume of pressure vessel: 13L Rated working temperature: 110 ℃± 5 ℃ Rated working pressure: 2.1MPa ± 0.01MPa External dimensions 630mm x 450mm x 500mm (length x width x height) PAV-1-2 asphalt aging vacuum box Power supply voltage: AC (220 ± 10%) V, 50Hz; Power 0.9kW Working volume of vacuum container: 13L Rated working temperature: 180 ℃± 5 ℃ Rated working pressure: pressure 15kPa External dimensions 560mm x 390mm x 350mm (length x width x height)
